The Economist writes: "IT HAD a green ogre and gang of huge shape-shifting robots on its side-but that was not enough to ensure victory for HD DVD, one of two rival high-definition video-disc formats fighting to become the successor to the DVD. On January 4th Warner Bros, a big Hollywood studio that had backed both HD DVD and the rival standard, Blu-ray, said it would drop its support for HD DVD from June 1st. This tips the balance decisively in favour of the Blu-ray camp (see chart). "Game over," said one analyst; HD DVD would now "die a quick death", predicted another. Blu-ray's triumph seems almost inevitable."
